1. 11. On Caries Risk Profiles Using Cariogram and Caries Prevention with Fluoridated Toothpaste in Orthodontic Patients

   Författare :Anas H Al Mulla; Dowen Birkhed; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Caries lesions. Caries model. Caries risk. Cariogram. QLF. Orthodontic bands. Saudi Arabia. Slurry rinsing. Toothbrushing. Toothpaste. Toothpaste technique. Water rinsin;

   Sammanfattning : Objective. The aims of this thesis were to: 1) analyse caries-related factors shortly after orthodontic treatment, 2) demonstrate the usefulness of the Cariogram by presenting orthodontic patients with different caries-risk profiles, 3) compare two different toothpastes with different post brushing techniques using an in situ caries model with orthodontic bands, and 4) test the hypothesis that toothpaste slurry rinsing, combined with some other simple post-brushing advice (in this thesis called the “modified F toothpaste technique, MFTT“), would reduce the number of decayed and filled tooth surfaces (DFS) in a 2-year randomised clinical trial in orthodontic patients.

   Sammanfattning : The postnatal development of the gastrointestinal (GI) system in mammals is genetically programmed, but is, to an unknown extent, regulated by external factors such as the diet and the gut microflora. These factors can influence the growth of the GI tract, the age-related pattern of appearance of digestive enzymes and the decreased intestinal macromolecular permeability at gut closure, normally timed with weaning in young rodents.

4. 13. Epidemiology and etiology of pancreatic cancer

   Författare :Jiaqi Huang; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Pancreatic cancer is one of the most devastating malignancies with an extremely high fatality, resulting that its mortality rate almost equals to incidence rate. Although primary prevention is of upmost importance, the underlying etiology of this cancer remains largely unknown. LÄS MER

   Sammanfattning : Allergy, which is the most common chronic disease in Swedish children and adolescents, is associated with a high standard of living and Western lifestyle. According to the hygiene hypothesis, allergy is due to inadequate stimulation of the immune system by microbes during early childhood, leading to failed maturation of the immune system. LÄS MER
